The team’s approach involves transmitting data in multiple modes within the O-band and the fundamental mode in ESCL-bands, leading to an increase in spectral efficiency. Dr. Donodin emphasizes the significance of this achievement in expanding data transmission capacity over existing fibers. The growing need for bandwidth, driven by data-heavy internet services and emerging AI applications, underscores the importance of this research. Supported by the Japan-Germany Beyond 5G/6G initiative, the team aims to further refine their systems and improve compatibility with current fiber networks.
The team presented their accomplishment as a post-deadline paper at the 51st European Conference on Optical Communication (ECOC) 2025 in Denmark last month. The collaborative effort involved contributions from 12 global institutions, including Fraunhofer Heinrich-Hertz-Institut and Nokia Bell Labs. Aston University’s participation in this project is supported by the EPSRC Programme grant TRANSNET, highlighting the university’s dedication to advancing photonic technologies within the evolving digital landscape.
